This fan is shown asoccupying an inclined position in relation to the separator; but it may,if desired, be arranged in any other convenient position, and, as amatter of fact, such fan structures are frequently arranged in ahorizontal position and also sometimes in a vertical position. Theegressopening develops into a curved neck 13 which leads up into theturn-table and forms a joint with the stump of the trunk or chute of thestraw-stacker, as best shown in Fig. 12. As will be best observed by aninspection of Fig. 18, the parts are peculiarly arranged. The dottedline 1') indicates the center of the fan structure, which, as it will beobserved, is half-Way between a line drawn through the axis of thefan-shaft and the adjacent side or wall b of the neck B which forms theegressopeningthat is to say, in the construction shown the fan casingbeing usually from forty to fifty inches in diameter, the fan-shaft isset about two inches to one side of a line drawn through its center,while the nearest edge of the neck forming the egress-opening is abouttwo inches to the other side of the center. The opposite side of theegress-openin gis shown as drawn in somewhat from a line parallel withthe center line b, or, in other words, slightly away from a linetangential to the peripheral wall of the fan-casing, and I regard thisas somewhat the best arrangement; but this outer wall may be on suchtangential line, as indicated by the dotted lineson Fig. 18, in whichcase the inner wall 12 of said egress-opening would be positionedsomewhat farther away from said center line b, so as to maintain theproper size of said egress-opening.

As will be observed, the peripheral wall of the fan-casing is so formedas that there is a somewhat constantly-increasing distance between theends of the fan-blades as they pass from what is usually known as thecutoff point x around to the egress-opening of the fan, this resultingprincipally by reason of the position of the fan-shaft, but alsosomewhat from the formation of the fan-casing. As will be readilyunderstood, with the arrangement of the eye or ingress-opening in thefan-casing and of the fan shown in Fig. 18 the most of the straw entersthe fan casing at that side nearest the egress-opening, and is thusalmost instantly discharged therefrom. This arrangement greatly reducesthe action of the fan-blades on the straw, so that it comes from themachine in a much less broken-up condition than where, as heretofore,most of it has been caused to travel around inside the fan-casingsubstantially an entire revolution. The power required is also obviouslyless. To secure the greatest efficiency the path of the fan-bladesshould be as near as possible to the peripheral wall of the fan-casingat the cutoff point 00, which is at the beginning of the neck formingthe discharge-opening The fan-shaft b I prefer to mount in two bearingssecured to the bottom of the fan-casing B, as best shown in Fig. 19,said bearings being preferably in the form of metal bars 17 b betweenwhich are wooden cross-bars b and the whole being secured together bybolts 5 The lower bearing is in the form of what is known as a stepbearing with a hard-metal bearingplate 19, against which the end of theshaft rests, and which takes the thrust of said shaft, with anadjusting-screw, by which its position may be adjusted, all as clearlyshown in Fig. 19. Mounted upon the shaft 12 is a bevel gear-wheel b,which, as shown in Fig. 3, engages with a corresponding bevel gearwheelon the shaft B on the outer end of which shaft is a pulley b to which abelt runs from some suitable shaft on the threshing-machine. Of course Ido not confine myself to a toothed gear for this purpose.

The turn-table, as shown in Figs. 11 to 17, inclusive, is made up ofthree parts 0'', C and C the parts 0 and 0 being fixedly secured uponthe framework, the part 0 by means of studs 0 and bolts 0 and the part 0being movably mounted between said parts 0 and 0 with grooves in theiropposing faces, which serve as tracks in which the carrier-trucks c ofthe movable part 0 run, as best shown in Fig. 12. The part C as bestshown in Fig. 16, is, generally speaking, a gear-ring, is provided withmeans whereby the stump of the trunk or chute of the straw-stacker maybe firmly attached thereto, and is also provided with trucks a which areadapted to travel in the tracks formed in the faces of the parts C 1 and0 As best shown in Figs. 11, 12, and 17, this gear-ring C has on itsinner edge an upwardly-projecting flange adapted to surround the stump Dof the trunk or chute, said flange being at substantially right angleswith the body of said ring. Firmly secured to said flange are two pairsof projecting arms C and C upon the former of which the yoke F ispivoted and by the latter of which the derrick H is carried. By thismeans this member O of the turn-table is adapted to conveniently carrythe entire upper structure of the straw-stacker, including the derrickand operating mechanism, at the properpoints, and thus said parts aremaintained in the same general relation irrespective of the position towhich the trunk or chute has been adj usted. The trucks 0 aresaucer-shaped in form, as best shown in Figs. 12 and 16. The portionsthereof which come in contact with the tracks are thus curved upon theouter sides, so that they are more easily guided in their movementsabout the tracks. The movable member 0 of the turn-table is preferablyoperated by a worm-gear C, suitablymounted in ears 0 on the lower member0 or upon the top of the separator alongside the turn-table. I haveshown a counter-shaft O with sets of spur-gears and an appropriateclutch, form- The parts C and C are provided 7 ing a mechanism forautomatically causing the trunk or chute to travel back and forth; butas this mechanism is not a part of my present invention it will not befurther described. Said mechanism is driven by a belt (not shown)running to a pulley c on this counter-shaft 0 When the automaticmechanism is disengaged, the position of the trunk or chute may beshifted by means of a hand wheel or crank c on the end of the shaftcarrying the worm C.

The trunk or chute is composed of the curved stump D,,which is fixedlysecured to the flange on the member 0 of the turn-table, asimilarly-curved section D adapted to move over said curved stump in theraising or lowerin g of the trunk or chute,and two telescoping straightsections 1) and D*, the latter of which surrounds and extends out beyondthe former. The section D has two ribs (1 on its upper side, which ribsare preferably formed of channel-iron, and between which is a clearspace for the passage of an operating cord or rope, while the ribsthemselves form rests upon which the outer section D may slide. Upon theextreme end of the section D is a ring or collar 1, which completelysurrounds the same. A short distance to the rear thereof, varyingpreferably from one to two feet, is another ring or collar 2, whichsurrounds said section ,exceptin g as to the space between the ribs (Zand at the extreme rear end of said ribs (1 there is another ring orcollar 3 similar to the ring or collar 2. In the extreme forward end ofthe space between the ribs (1 close to the ring or collar 1 is secured asheave or pulley 4, which, while preferably revoluble, may be fixed, asbest shown in Figs. 4- and 7, the purpose of which will presently beexplained.

The section D is somewhat larger than and surrounds the section D At itsextreme rear end it has an interior band or collar 5, which extendsaround the same, except as to the space between the ribs d on thesection D and it also preferably has an exterior band or collar 6 partlyor wholly surrounding it at the same point. The section D movestelescopically upon the section D but this operation will beparticularly described in connection with the operating mechanism. Atthe forward end, as best shown in Fig. 6, this section D has an openunder side formed by cutting away a portion of the cylinder structureforming said section D and securing in place thereof the straight sidesD and the opening so made forms the greater part of the egress-openingfor the straw, from which it falls to the stack or mow.

The hood E is composed of numerous sections c e zc. all mounted upon thepivots c,

which are carried by theextreme lower and forward corners of the sideplates D These sections are connected together by a chain E, one end ofwhich is connected suitably to the upper side of the trunk or chutesection D. An arm E is rigidly connected to the lower hood-section e,and when rocked operates to raise said hood-section, which in turnoperates the other sections, thus giving said hood as a whole a positionby which it is enabled to deflect the straw issuing from the trunk orchute to a greater or less extent. Normally this arm is held to thatposition which holds the hood to its extreme extended position by meansof a torsional spring E but it is adapted to be pulled back to anyextent desired by the cord or rope 9 running back to the operatingmechanism, as will be presently described. The chain E holds the partsin their proper relative position at all times and prevents any of thesections from dropping out of proper relation to the adjacent sections.

The yoke F, as shown most plainly in Fig. 8, has a central opening,which surrounds the part D of the trunk or chute and serves, through themechanism which will be presently described, to support or carry themovable portion of said trunk or chute as a whole. Its legs F arepivoted on the pivot-shaft 0 carried by the arms 0 on the turntable. Anextension F projecting upwardly from the upper side of the ringsurrounding the trunk or chute, carries the shaft G of the windingmechanism and also the shaft of a sheave 7L2, around which the rope fromthe hoisting-derrick passes.

The shaft G is mounted in the upwardlyprojecting extension F of the yokeF and carries rigidly attached thereto the circular rack or detent G,the winding drum or spool G and the circular rack or detent G and alsocarries loosely mounted thereon the winding drum or spool G It furtherhas a handwheel G having a handle 9 by which said shaft and the partscarried thereby are turned. The looselyunounted spool G carries aspringpawl 9 which engages with the circular rack or detent G Thedetails just described are best shown in Figs. 8, 9, and 10. As mostplainly shown in Figs. 4 and 5, a rope g" is wound about the spool G andthe ends of said rope run forward and are connected to the section D ofthe trunk or chute at its extreme rear end, where it bears the band orcollar 5, one end of which rope, however, first passes under said bandor collar to the sheave at, secured to thefront end of the trunk orchute section D -By this means by revolvin g the shaft in one or theother directions the outer section D of the trunk or chute can beadjusted to project more orless and the length of the trunk or chute asa whole thus determined, as may be desired. The ribs (Z and the band orcollar 1 form a space within which the rope 9 may pass to inside thechute-section D where it passes around the sheave 4 or its equivalent.By this means I am enabled in a telescopic trunk or chute to dispensewith all exterior tracks or supports, thus greatly simplifying, as wellas improvin g,this feature in a pneumatic straw-stacker. The position towhich the movable section D of the chute is projected, especially whensaid chute stands at a considerable elevation, is maintained by the pawlg, carried by the frame F which engages with the circular rack or detentG on the shaft G.

A single rope 9 runs from the looselymounted winding drum or spool G tothe upper end of the arm E as best shown in Fig. 5, and is adapted tooperate reversely to the spring E The spool Gbein g loosely mounted canbe revolved independently of the shaft Gr, While it is normally held torevolve with said shaft G by the pawl g which engages with thefixedly-mounted circular rack or detent G To raise or lower the hood, itis only necessary to disengage this springpawl g and revolve the spool Gto the desired point, after which by permitting the pawl g to againengage with the ratchet the parts will be held to adjusted position. Inthe moving of the telescopic section back and forth, however, therelative position of the hood is not changed, as the diameter of thespool G is proportionally the same as that of the spool G so that therope g is paid out or drawn in uniformly with the movement of saidtelescopic section D The hood therefore needs no attention in theordinary manipulation of the telescopic trunk or chute, but is operatedindependently, notwithstanding its operating drum or spool is upon thesame shaft as that by which the telescoping operation is effected.

The position and operation of the hoistingderrick are best shown in Fig.5. This derrick consists of the upright frame H, mounted on the sameportion of the turn-table as that whichcarries the yoke F and carries inits upper part a winding drum or spool 11, from which a rope H runs tothe sheave 7L2 on the top of the yoke structure and returns thence andis connected to the frame H of the derrick. Upon one end of the shaft ofthe spool H is a screw-gear h, and running transversely to this is aworm H operated by a hand wheel or crank 1-1 The frame His stronglybraced by braces h and, as before explained, travels with theturn-table, so that the pull on the ropes is always in the samedirection irrespective of the position of the straw-stacker.

Having thus fully described my said invention, what I claim as new, anddesire to secure by Letters Patent, is
